The study of plastic particles, particularly those in the micro-, sub-micro-, and nano-size ranges, within food and beverages has gained increasing interest within recent years. However, many analytical techniques have limits of detection which hinder their use for the study of these particles in these sample matrices. In addition, remaining contaminants from the matrices can interfere with the signals from plastic particles. Thus, great care must be given to sample preparation and data interpretation to ensure accurate results. This study proposes the use of sample purification through chemical digestion protocols to facilitate the study of plastic particles present in tea samples, and serves to highlight technical limitations which must be overcome in future studies.

Cannabis production standards are evolving with little understanding of their implications on land use planning. Health Canada currently administers a federally-regulated licensing system that does not address odour and light pollution land use impacts across the rural landscape. This literature review addresses the regulatory history of cannabis production in Canada, reviews current production standards, and compares possible cannabis production conflicts with documented land use conflicts from other odourous and light intensive operations to reveal flaws in the existing licensing system. Established cannabis production markets will be examined for further comparisons.

In this paper, we consider what we identify as crisis surveillance capitalism in higher education, drawing on the work of Naomi Klein and Shoshana Zuboff. We define crisis surveillance capitalism as the intersection of unregulated and ubiquitous data collection with the continued marginalization of vulnerable racial and social groups. Through this lens, we examine the twinned crisis narratives of student success and academic integrity and consider how the COVID-19 pandemic further enabled so-called solutions that collect massive amounts of student data with impunity. We suggest a framework of refusal to crisis surveillance capitalism coming from the work of Keller Easterling and Baharak Yousefi, identifying ways to resist and build power in a context where the cause of harm is all around and intentionally hidden.

Introduction: The lack of policy, practice and research action on physical activity and features of the physical (built and natural) environments in rural, remote and northern settings is a significant threat to population health equity in Canada. This paper presents a synthesis of current evidence on the promotion of physical activity in non-urban settings, outcomes from a national priority-setting meeting, and a preliminary call to action to support the implementation and success of population-level initiatives targeting physical activity in non-urban settings. Methods: We conducted a “synopses of syntheses” scoping review to explore current evidence on physical activity promotion in rural, remote, northern and natural settings. Next, we facilitated a collaborative priority-setting conference with 28 Canadian experts from policy, research and practice arenas to develop a set of priorities on physical activity in rural, remote and northern communities. These priorities informed the development of a preliminary Canadian call to action. Results: We identified a limited number of reviews that focused on physical activity and the built environment in rural, remote and northern communities. At the prioritysetting conference, participants representing rural, remote and northern settings identified top priorities for policy, practice and research action to begin to address the gaps and issues noted in the literature. These priorities include self-identifying priorities at the community level; compiling experiences; establishing consistency in research definitions and methods; and developing mentorship opportunities. Conclusion: Coordinated action across policy, practice and research domains will be essential to the success of the recommendations presented in this call to action.

Introduction. L’absence d’interventions en matière de recherche, de pratiques et de politiques relativement à l’activité physique et les particularités de l’environnement physique (bâti et naturel) en milieu rural ou éloigné et dans les régions du Nord constituent des freins importants à l’équité en santé de la population au Canada. Cet article présente une synthèse des données probantes pertinentes sur l’activité physique en milieu non urbain, les résultats d’une rencontre sur l’établissement de priorités nationales ainsi qu’un appel préliminaire à l’action en vue de favoriser la mise en place et la réussite, à l’échelle de la population, d’initiatives axées sur l’activité physique en milieu non urbain. Méthodologie. Nous avons d’abord réalisé un examen de la portée des synopsis de synthèses pour étudier les données probantes pertinentes en lien avec la promotion de l’activité physique en milieu rural, éloigné ou naturel et dans les régions du Nord. Nous avons ensuite organisé une conférence à laquelle ont pris part 28 experts canadiens spécialisés en politiques, en recherche et en pratiques, afin de concevoir de manière concertée un ensemble de priorités sur l’activité physique en milieu rural ou éloigné et dans les régions du Nord. À la suite de cette rencontre, nous avons rédigé un appel à l’action préliminaire pour tout le Canada. Résultats. Nous avons relevé relativement peu de travaux axés sur l’activité physique et l’environnement bâti en milieu rural ou éloigné et dans les régions du Nord. Lors de la conférence sur l’établissement de priorités, des participants représentant des milieux ruraux ou éloignés et des collectivités du Nord ont formulé les grandes priorités d’action en matière de politiques, de pratiques et de recherche pour commencer à réduire les écarts et résoudre les problèmes soulevés dans la littérature : le besoin d’identification au niveau communautaire; la compilation d’expériences; l’assurance d’une cohésion dans les définitions et les méthodes de recherche et enfin la création de possibilités de mentorat. Conclusion. Une action concertée entre les domaines des politiques, des pratiques et de la recherche est essentielle au succès des recommandations formulées dans cet appel à l’action.

Background: There exists a major disparity in access to specialist care between patients in urban and rural areas. Specialists are a scarce resource and are concentrated in urban areas. Specialist outreach attempts to fill the gap in service provision for patients situated remotely. While there is international evidence that multifaceted specialist outreach has achieved varying levels of success, factors that influence the effectiveness of outreach have not yet been fully elucidated in South Africa. Aim: This study attempts to uncover some of the factors that enable good multifaceted specialist outreach. Setting: The study was conducted in hospitals in western KwaZulu-Natal province. This health area is served by a tertiary hospital and 20 peripheral hospitals; three of these are regional level and the majority are district level hospitals. Specialist outreach emanates from the tertiary hospital. Methods: Specialists providing outreach services from the tertiary hospital and medical officers at seven receiving hospitals were interviewed to explore perceptions regarding factors that might enable successful specialist outreach. Framework analysis on the transcribed interviews was carried out using NVivo version 11. Results: A major positive finding concerns the relationships formed between outreach specialists and doctors at the recipient hospitals. The management of the programme with respect to structure, dependability, data management, transport provision, communication technology and public health systems was also seen as beneficial in specialist outreach. Conclusion: Specialist outreach plays an essential role in providing equality in health care. To enable effectiveness, it is important to make full use of the multifaceted nature of this intervention.

The article focuses on the notion of a common public culture in the province of Quebec. According to the author, no political consensus on this concept has been observed and the definition of a common public culture is to be called into question. The author bases the article on the criticism of the book "Du tricoté serré au métissé serré? La culture publique commune au Québec en débats," by Stephan Gervais. The topic of the government policy on immigration is discussed, as well as the notion of cultural transmission.
